Eyes are one of the most valuable and delicate organs of our body. There is a clear lens in the eye that allows you to see clearly. But when this lens gets cloudy, you need cataract surgery to replace the opaque natural lens with an artificial lens called an intraocular lens (IOL).
With enormous advancements in the medical domain, today we have a huge variety in IOLs to choose from. Your eye specialist will explain to you the different IOLs, how they work, and which one would be suitable for you. The factors to be considered include your lifestyle, visual needs, and budget.
Let us have a quick look:
1. Monofocal IOLs
The most commonly used lenses, monofocal lenses offer clear vision at one fixed distance, which is usually far. There is a high likelihood that you will still need glasses for reading or close-up work. They are affordable and widely covered by insurance.
2. Advanced Monofocal IOLs
As the name suggests, these are an advanced version of the traditional monofocal lenses. These lenses offer improved contrast sensitivity and better quality of vision, especially in low-light conditions.
Just like monofocal lenses, advanced monofocal IOLs also provide focus at one distance (usually far). The additional advantage is that their design often reduces visual disturbances like glare and halos so that you get a more refined visual experience. They are advised for patients who want enhanced clarity but do not mind using glasses for near or intermediate tasks.
3. Multifocal IOLs
These lenses are designed such that you can see clearly at more than one distance – near, intermediate, and far. They have rings within to split light for varying focal points. A variety of these lenses is – trifocal lenses – which have 3 separate focuses for different distances.
While these lenses may eliminate your need for spectacles, you may experience glare or haloes, especially at night.
4. Extended Depth of Focus (EDOF) IOLs
They are an advanced type of IOLs designed in a way to give you a continuous vision range, particularly from far to intermediate. They are frequently advised for people who work on computers.
While they offer better intermediate vision than traditional monofocals, you may still need reading glasses for fine print.
5. Toric IOLs
Toric IOL lens is specifically designed to correct astigmatism – which occurs due to non-spherical shape of the cornea. They are available in different powers – monofocal, advanced monofocal, and multifocal variants.
